I cant argue with someones’ nan’s facebook feed telling them outright lies, but there is a hell of alot of misinformation being peddled - and not just from anti-EV people. Some very pro-EV people also talk total shit. If you havnt considered it, why not?
Tbh in my old ICE I would have done the same as you - stopped as little as necessary. EV driving lends itself to a different mindset, and I stop much more often (even if it’s a quick ten minute top-up at some stops). It’s more relaxing but until you need to think different and plan ahead, you don’t realise it will change your habits (I certainly didn’t). Of course, traveling through the desert likely has it’s own complications and probably insufficient charging points, which might be a bigger consideration.
